TLDR
In this article, an instantaneous direction changing rotation mechanism was proposed for transmission via either a direction changing train of gear with negative train value or casing of gear for driving the driven shaft for rotation in either reverse or normal direction.Abstract:
An instantaneous direction changing rotation mechanism in which its driving shaft and driven shaft have coincident central lines, the driving shaft can be controlled for transmission via either a direction changing train of gear with negative train value or casing of gear for driving the driven shaft for rotation in either reverse or normal direction; the intermediate bevel gear of the train of gear has a spindle extending to the exterior of the casing of gear and fixed to a brake block so that the above control can be achieved by engaging or disengaging the brake block with a barke element; a movable ring is surrounding the upper part of the casing of gear so that while the rotation of the movable ring is restricted by the sensor means, there is an angular displacement against the casing of gear for disengaging or engaging the brake element with the brake block.read more

Drive coupling and clutches
TL;DR: In a cone clutch, a set of radially distributed helical surfaces in a cone cone clutch axially urge movable cone members selectively into engagement with either of two mating cone members thereby enabling a clutch output member or members to be driven in either rotary direction.
Patent
Drive couplings and clutches
TL;DR: Differential gear sets and planetary gear sets in combination with sets of corresponding radially distributed helical surfaces in drive couplings such as cone clutches allow axial movement of the cone members of a clutch selectively into engagement with either of two mating cone members thereby enabling an output member to be selectively driven bidirectionally.
